Fish Stocking Activity

Year Species Size Number Pounds
2013 Walleye fry 100,000 1.0
2012 Walleye fry 100,000 0.9
2011 Walleye fry 100,000 0.9

2007 Channel Catfish yearlings 114 114.0
  Walleye fingerlings 2,628 108.0
2005 Walleye fingerlings 1,820 54.0

Privately Stocked Fish
* indicates privately stocked fish. Private stocking includes fish purchased by the DNR for stocking and fish purchased and stocked by private citizens and sporting groups.

Stocking Fish Sizes
Fry - Newly hatched fish that are ready to be stocked usually called "swim-ups". Walleye fry are 1/3 of an inch or around 8 mm.
Fingerling - Fingerlings are one to six months old and can range from a size of one to twelve inches depending on the species. Walleye fingerlings range from three to eight inches each fall.
Yearling - Yearling fish are at least one year old. A one-year-old fish can range from three to twenty inches depending on the species. Walleye yearlings average from six to twelve inches.
Adult - Adult fish are fish that have reached maturity. Depending on the species, maturity can be reached at two years of age. Walleye reach maturity between the ages of four and six years.

Status of the Fishery (as of 06/08/2009)

Silver Lake is a small (114-acre), natural, prairie lake located three miles south of Hawley, MN. It's the only lake in Clay County with no history of winterkill. Since the lake is located on the far western edge of the lakes' area and is within 25 miles of the Fargo-Moorhead metropolitan area, it is subject to heavy recreational uses including water skiing, fishing, swimming, and jet skiing. The lake's small size and lack of vegetative cover make it vulnerable to over-harvest of fish.

Fish populations have improved greatly since Silver Lake was chemically reclaimed in 1985. Prior to the treatment, the lake had become infested with undesirable fish like black bullhead and carp. Walleye, bluegill, black crappie, largemouth bass, yellow perch, channel catfish, and spottail shiner were all reintroduced following treatment. During the twenty years since then, northern pike, white sucker, and black bullhead have also found their way back into the lake.

Walleye and channel catfish fisheries are sustained by regular stocking. Bluegill, black crappie, largemouth bass, and yellow perch reproduce naturally in Silver Lake. Populations of these species would probably do better with the presence of emergent plant cover like bulrush, but they are maintaining modest populations.

Northern pike grow rapidly in Silver Lake during their younger life stages. Although the potential to grow extremely large pike is better in lakes with deep, cool, well-oxygenated waters with populations of tullibee (cisco), Silver Lake produces pike over 30 inches regularly if they are not harvested first. Anglers are encouraged to voluntarily release pike longer than 24 inches in length and to keep smaller ones for eating.

It is hoped that gamefish populations will continue to help suppress populations of fish like black bullhead and white sucker. Chemical treatment is an extremely expensive last resort. Anglers are urged to make sure not to accidentally introduce unwanted fish or other invasive species into the lake by dumping minnow buckets or draining bilges or livewells after fishing other lakes.
